JakeG,
I received the invoice today. The new FP's are in heat treating at this moment. They have already been cut and are finished. I should take delivery the end of July. I have several project 97's waiting on this new FP.
heavypat12,
Not as much as you would think. The hammer hook depth and angle are the biggest determinates. However, the hammer spring does influence the SA pull somewhat. Unfortunately, a lighter HS will magnify the amount of creep in the trigger/hammer.
